Where's the App list?

All of the apps and games on your Windows Phone can be found in the App
list—just swipe over from the Start screen to go there. You can pan up or down
in the App list to see your installed apps, or tap a letter to jump to a
section of the alphabet.

Your apps don't need to stay put in the App list, of course. You can
tap and hold any app to
pin
it to Start or to uninstall it. (Some important apps that come
with your phone, like Phone and
Alarms ,
can't be uninstalled.)

The App list is also the place where you can check the status of an app
download or installation. If there's a problem with an app, you can usually tap
Attention required below the app name to get more information.
